RAIL-JOINT CHAIR.

Specification of Letters Patent.

- Patented Sept. 30, 1919.

Application filed May 25, 1918. Serial No. 236,447.

To all whom it may concern."

Be it known that I, JEFFERSON D. I-IUEY, a citizen of the United States,residing at the city of St. Louis and State of Missouri, have invented anew and useful Rail-Joint Chair, of which the following is aspecification.

This invention relates to improvements in rail joint chairs and consistsin the novel construction hereinafter disclosed.

An object of the invention is to provide a rail joint chair which may bereadily-assembled in respect to adjacent ends of the rail for supportingthe same, and which will be durable in construction and efficacious inreducing the jar and strain upon the track construction at the joints ofthe rail.

Another object of the invention is to provide a rail joint chair whichmay be easily applied for supporting the rails at the adjacent ends andreadily removed for purposes of repair, which will remove from the railat the joints all strain in a vertical direction and which provides forthe normal expansion and contraction of the rails.

Another object of the invention is to pro vide a rail joint chair whichembraces the side Walls of the rail at the jointsand constitutes asupport for the bottom of the rail, thereby reducing the wear upon thetrack construction at the joints and providing a continuouswheel-carrying surface throughout the length of the track constructionin which the invention is embodied.

With the foregoing as well as additional advantages attainable from theconstruction in view, I have designed a rail joint chair as hereinafterfully desoribed,.reference being.

made to the accompanying drawing, in wh1ch Figure 1 is a plan viewillustrating the construction of the present invention.

Fig. 2 is a s1de elevation of the rail oint chair embodymg thelnventlon.

Fig. 3 is a side elevation of the opposite side of the rail joint chairof the invention.

Fig. 1 is an end elevation with a section through the rail of theconstruction of the invention.

Fig. 5 is a cross section taken through the rail joint chairconstruction and the rail, taken substantially on the line 5-5 of Fig.1.

Fig. 6 is a sectional detailed view illustrating the means employed forlocking the nut of the retaining bolts.

In the embodiment of the invention illustratcd in the drawing, the railjoint chair proper con'iprises a base 1 which has integrally formedtherewith a riser 2 which extends inwardly from the base and has aninner surface which conforms to the contour of the side of the rail,thus forming a longitudinal groove 3 into which one of the side flangesof the T-rail extends, a filler port-ion L which extends into the spaceformed exterior of the web of the rail, the upper portion of said filler4 constituting a shoulder 5 extending under the lower surface of theball of the rail. The upper por tion of the riser extends adjacent tothe side wall of the ball of the rail and has a flange 6 which overhangsthe side edge of the ball of the rail. The upper surface of the riserslopes upwardly toward the center forming an inclined surface which isin approximately the same plane with the upper surface of the ball ofthe rail at the extremities, and slightly elevated as indicated at 7above the upper surface of the rail at the joint.

Thus when the flanged Wheels running upon the rail approach'the railjoint, the weight is received and carried by the upper surface of theriser so that when the weight is over the joint it is entirely supportedby the riser of the rail joint chair, relieving the rail from verticalstrain. The horizontal alinement of the rail extremities is maintainedthroughout by the support afforded by the chair so that the trackconstruction is maintained in perfect alinement. 7

At the side edges and upon both sides of the base section are extensions8 which are provided in their outer edge with channels 9 for receivingspikes for attaching the chair in position on the ties of the railconstruction.

The opposite side of the base from that from which the riser 2 extendsis formed with alternate extensions and cut-out portions 10 and 11respectively. A filler piece comprising knuckles 12 adapted to seat inthe cut-out portions 11 of the base section and an angular plate, formedintcgralthercwith including a horizontal wall 13 and a Wall 14 formedsubstantially at right angles thereto, constitute a support for theopposite side of the rail, the wall 13 fitting over the upper face ofthe lower flange of the rail and the wall 1% bearing against the web ofthe rail and supporting at its upper edge the under face of the ball ofthe rail.

air M;

to receive a tie-rod or bolt 16 which, after.

insertion in said openings, is held at one end by a bolt head 1 and atthe other end by a cotter pin 18. A series of registering openings 19,20 and 21 are formed respectivel in the wall 1s of the filler piece inthe we of the rail and in the riser.

In applying the rail joint chair to the rails the lower flange of therail is positioned on the upper face of the base of the rail joint chairand one side of the rail is brought into close contact with the innerface of the riser section. The filler-piece is then placed in positionagainst the other side face of the rail and the rod 16 adjusted inplace. The filler piece is then clamped in position by the series ofbolts, the heads 23 of which bear against the wall 14: of the fillersection. The diameter of the openings 19, 20 and 21 is in excess of thediameter of the shanks of the bolts, so as to permit. a longitudinalmovement of the rails in the rail joint chair caused by the normalexpansion and contraction. The tie.

bolts are held in locked position by a series of inner nuts 24 and locknuts 25.

In order to facilitate the assembly of the tie bolts the riser sectionis formed with longitudinal channels 26 and recesses 27 The recesses 27have their inner surfaces formed so as to provide alternate teeth andintermediate spaces as indicated at 28. The lock washer has a: basesection 29 the outer surface 30 of which is formed withcomplementarilyformed teeth and recesses to fit into the teeth and recesses of the sidewalls of the recesses 27 in the riser section. The'inner face ofthe lockwasher is polygonal so as to fit over the outer nut 25 carried by thetie bolts.

Projecting outwardly from the base section 29 of the lock washer areflanges 31 which embrace the side edges of the outer nut 25. In thesides of the nut 25' are grooves 32 and in the inner surface of theflanges 31 are grooves 33. The lock washers are inserted in the recesses27 of the riser portion and over the two nuts carried by the tie bolts.The matching faces of the recesses and of the base section of the washerprevent the washer from turning. Pins 34 are then inserted in channelsformed by the matching faces of the grooves 32 in the nut and 33 in theflanges of the washer after the bolts have been drawn to the properadjustment. 7 I

This construction prevents the loosening of the bolts and holds thempermanently in position regardless of the vibration caused Copies ofthis patent may be obtained for by the wheels running over the joint,thus preventing loosening of the parts.

It will be observedthat when the rail joint chair is thus assembled withadjacent ends 'of rails, a rigid clamping support is provided forpermanently holding the rails in alinement and affording supportthroughoutthe surface of the rails, with the exception of the topsurface of the ball of the rail from which strain is removed by theupper face of the riser section at the joint.

It will also be observed that the construction permits the readyassembling of the-rail joint chair with the rails, and that the same maybe removed for purposes of repair or adjustment without destroying anyof the parts thereof, permitting the re-assembling of the constructionwithout loss of material.

I am aware that the invention may be modlfied in I numerous particulars,without departure from the spirit and scopeof the invention. 7

What I claim and desireto secure by Letters Patent, is V 1. A rail jointchair, comprisinga base; extensions projecting laterally from each sideof the base and having notches in-their outer'ends adapted to receivethe spikesface inclining upwardly from each end to an elevation abovethe surface of the rail mldway between the ends of the chair; and

means for clamping thevfiller and the riser;

against the rail. 7

:2. A rail joint chair comprising a base; extensions projecting*laterally from each side of the base and having notches in their outerends adapted to receive the spikes securing the chair to the ties; a rodpassing through said extensions at one-side of the base between saidnotches .and'the bodyof the base; a filler pivoted to said rod andhaving its outer side inwardly from said notches to permit the heads ofthe spikes to engage said extensions; a riser at the oppositesides ofthe base having an upper surface inclining upwardly from each 'end to anelevation above the surface of the rail midway between the ends of thechair; a

flange on the inner side of said riser'bearing upon the upper surface ofthe head of the rail; and means for clamping the filler and the riseragainst the rail.
